One way to reduce dynamic friction in advanced productive nanosystems is to reduce bearing surface area.
And one way to do this is by transporting parts/components in batches.
There are other ways too. See sections further below.

In gem-gum on-chip factories
Instead of many individual attachment chains carrying parts (fills 1D volume)
an option may be to have a wide attachment chain carrying many small parts side by side (2D volume).
Furthermore they may be stacked such that the attachment chains carry part carrying lamellas (3D volume).
This might be especially relevant for the input transport channels crossing sublayers.
See: Optimal sublayernumber for minimal friction
In microcomponent distribution systems
See: Capsule transport
Other means of reduction of friction losses by change of bearing area (not only decrease)
Minimizing bearing surface area is not as effective as reducing operation seeds.
– But once quadratic efficiency gains from slowdown are maxed out (1/10th the speed => 1/100th the losses)
– Reducing bearing contact area can still give some linear gains (1/10th the area => 1/10th the losses)
Note that initial gains from slowdown are diminished by
an increase in surface area from more machinery fully compensating the loss in throughput
So effectively it's only a linear gain in efficiency.
For details see: Increasing bearing area to decrease friction
Subsequent sole focus on reduction of bearing area excludes reduction of number of machinery.
It only focuses of bearing surface area per machine unit.
Machine unit like e.g. a mechanosynthesis core.
Macroscale friction power losses (normal-force x friction-coefficient x sliding-speed)
is not area dependent but it's contribution to total friction is negligable.
